Description

  • Dragino SE01-LB LoRaWAN Soil Moisture & EC Sensor (US915)
  • Measures soil moisture, temperature, and conductivity
  • Utilizes LoRa technology for long-distance data transmission
  • Ensures accurate readings with FDR method
  • Supports BLE configuration and OTA updates
  • Powered by long-lasting battery or solar panel options

The Dragino SE01-LB LoRaWAN Soil Moisture & EC Sensor (US915) is an advanced device designed for agricultural IoT applications. It measures soil moisture, temperature, and conductivity, specifically calibrated for saline-alkali and loamy soils. Utilizing the Frequency Domain Reflectometry (FDR) method, it ensures accurate soil moisture readings by compensating for soil temperature and conductivity variations.

This sensor employs LoRa wireless technology, enabling it to transmit data over long distances with low data rates, ensuring robust communication with high interference immunity while conserving power. The device supports Bluetooth Low Energy (BLE) configuration and wireless over-the-air (OTA) updates, enhancing user convenience.

Powered by an 8500 mAh Li-SOCI2 battery or a combination of solar power and a lithium-ion battery, the SE01-LB/LS is designed for long-term use, with a lifespan of up to five years. Each unit comes pre-loaded with unique keys for seamless LoRaWAN registration and automatic connection upon activation.
